Collidable component

Entities with a collidable component are used in collision detection. This is used e.g. in ships, but not projectiles (unless they should collide with other projectiles). For example, if volumes of a collidable ship and non-collidable projectile intersect, collision is detected - the projectile hits the ship. Same for two collidable ships. But if volumes of two non-collidable projectiles intersect, there is no collision; the projectiles just continue moving as before.



Currently, this component has no parameters, but some collision detection parameters might be added in future. A Volume component is needed to actually have a volume to detect collision with.
